MIDI Controller iCON P1-Nano Connection

Hi
I’m trying to make friends with the iCON p1-Nano controller. I can’t figure out the logic in any way. Some features work. The fader doesn’t want to work at all. I assign the Alt+M command to the touch button, it doesn’t work. From the keyboard, everything is ok.

Mmm, so which one is it? Either it doesn’t work, or everything is OK. Could you please elaborate?

What platform are you on? If Linux, which audio/MIDI backend? If JACK/Pipewire, which version of Pipewire?
